Wife Olivia Stretched. Hung Cal, #3

Olivia and her husband are at their destination beach house for the weekend. Their host is a huge surfer guy - a powerfully built Adonis who Olivia has agreed to have sex with. It's the arrangement married couples must commit to when lucky enough to secure a highly competitive weekend booking here. The husband is placated by the services of a part-time female prostitute. The wife is to be repeatedly ravaged by the extremely well-hung owner of the beach house.
Both Olivia and her husband Keith are up for this, though they're quite nervous about it. Olivia is afraid of the sheer physical presence of this man - his size and the rumoured size of his genitalia, also his apparently insatiable libido. Keith is unsure of how he's going to cope with knowing his wife is in an adjacent bedroom of the small beach house with this other man.
